Sure, you’re trying to be “respectful” by denigrating our support for Thompson as “enthusiasm for a candidate with a presence on the silver screen.”
I do not denigrate you for supporting Fred Thompson, but do not hesitate to question him on some matters - just as I have with Romney, Huckabee, McCain, and (especially) Giuliani. Never, to my recollection, have I referred to those other men using derogatory names, and I went out of my way to acknowledge Giuliani's stellar post-9/11 leadership even though I oppose most of what he stands for.
It is my hope that you, likewise, would show respect for those with whom you disagree (e.g. calling them "gnats").
